An affogato (Italian for "drowned") is a coffee-based drink or dessert. "Affogato style", which refers to the act of topping a drink or dessert with espresso, may also incorporate caramel sauce or chocolate sauce. When ordered, an Affogato tends to be served with scoops of ice cream with a shot (or 2) of espresso poured over the top, sometimes mixed with a liqueur. A white Affogato is the same as a regular Affogato, just with milk added.
I never fully understood how K-Cups worked until I got my own machine. Each little pod is basically a small packet of coffee grounds. The machine pokes a hole in the top and bottom of the packet that the water drips through, just like a mini version of a big coffee maker. The small serving size and ease of clean-up makes for the perfect cup with no hassle. We even take our machine camping sometimes!
Good news to all those coffee lovers out there: That cup of joe has quite a few health benefits, as long as you don't load it up with cream and sugar. A number of health organizations agree: The World Health Organization in June 2016 took coffee off the list of potentially carcinogenic foods, stating that java possibly protects again certain cancers, while the 2015 Dietary Guidelines Advisory Committee declared that three to five cups of coffee a day can be part of a healthy dietary pattern. In fact, research shows that black coffee can have a positive effect on conditions including diabetes, dementia and depression.
